To mount a microcircuit module in a cavity in a card forming a support, resin is deposited on the bottom of the cavity and the module is fitted in such a way that the microcircuit is coated with resin. A compressible annular area formed in the cavity completely surrounds the microcircuit and the coating material. The annular area extends over a continuous peripheral area of the bottom of the cavity.

Method for mounting a microcircuit in a cavity of a card forming a support and resulting card

A method of fabricating a microcircuit card provides better control of the spreading of a hardenable coating material during fabrication of the microcircuit card. The surface of a support is treated to define at least two areas with different surface states and both extending beyond a predetermined location of the microcircuit. The deposit of the material is delimited by the configuration of these areas. The treatment is preferably applied by means of a laser beam.
